d. The vent terminal shall not be less than 2 feet from an adjacent building. e. The vent terminal shall not be less than 7 feet above grade when located adjacent to public walkways. f. The vent terminal shall not be located so that flue gasses are directed to jeopardize people or overheat combustible structures, materials or enter buildings. g. All joints in the vent system are to be sealed with Permatex high temperature sealer or equivalent to prevent the leakage of products of combustion into the building Text Box: WARNINGGGG Text Box: Caution 3. COMBINATION AIR INTAKE/VENT SYSTEM The vent system consists of 10, 15, or 20 foot lengths of 5” single wall flexible stainless vent piping, or 10 or 15 foot lengths of double wall insulated flexible stainless vent piping and an equal length of 4” air intake piping and a stainless steel intake/vent termination end. Consult the Direct Vent manual included with the direct vent kit for more detailed installation instructions. The hole thru the wall for the vent termination end should be .” larger than the vent termination end itself or approximately 7 .” square. Install the vent termination thru the opening in the wall centering it in opening. Apply a bead of silicone caulking around the perimeter of the vent termination end. Attach the termination to the house by screwing it fast thru the holes in the termination end. Install the flexible vent piping with the provided connector between the boiler and the termination end. The joints at the boiler, vent connectors, and termination end should be securely fastened and must be sealed with high temperature silicone to prevent leakage of flue gasses. THE MINIMUM DISTANCE TO COMBUSTIBLE MATERIALS FROM THE 5” SINGLE WALL VENT PIPING IS 9”. THE MINIMUM DISTANCE TO COMBUSTIBLE MATERIALS FROM THE 5” DOUBLE WALL INSULATED VENT PIPING IS 2”. CONSULT NFPA-31 FOR REDUCED CLEARANCES. The air intake must be installed to the air inlet collar on the combination vent hood and to the burner. The air intake kit consists of one 4” galvanized elbow, one 4” galvanized tee, one vacuum relief valve (barometric damper), and one length of 4” flexible piping. The vacuum relief valve (barometric damper) is to be assembled and then installed in the 4” tee with the hardware provided. Install the fresh air intake duct tee and damper as close as possible to the burner. The purpose of the damper is to act as a vacuum breaker in the event of a blockage in the air intake. NOTE: The balance weight of the vacuum relief valve must be installed in a level position and adjusted to lightly close while burner is operating. Be sure to lock the balancing weight after adjustment. ALL JOINTS IN THE AIR INTAKE ASSEMBLY MUST BE SECURELY FASTENED. THE MAXIMUM LENGTH OF FLEXIBLE AIR INTAKE DUCT, WHICH CAN BE RUN TO THE BURNER, IS TWENTY FEET PLUS THE LENGTH THAT RESULTS FROM THE 4” TEE AND 4” ELBOW SUPPLIED. DIRECT VENT OIL BURNERS Riello Burners All Riello direct vent burners are shipped with the nozzle for the SLD375 installed. A separate nozzle is included in the burner carton for the SLD4100 and SLD5125. See the burner set up page or the Installer Serviceman Label attached to the boiler. for the appropriate burner settings. Boilers supplied with Riello burners will also be supplied with a 3” to 4” galvanized adapter. The adapter is to be fastened directly to the flange opening on the burner cover using three sheet metal screws. The Riello BF5 burners for use with direct vent systems are shipped with the controls, which provide pre and post purge. Pre purge is provided to ensure clean starts under all conditions. Post purge is provided to ensure that the boiler fires at maximum efficiency and dependability throughout the heating season. Post purge timing is variable. The factory set post purge timing should be set at approximately 45 seconds. Post purge times in excess of 60 seconds when using the Riello burner will cause the Honeywell Aquastat to lock out on an error code Err4 B1 fault. Beckett Burners Boilers supplied with the Beckett NX burner are supplied with an inlet air adapter which must be installed in place of the inlet air louvers. Refer to the Beckett NX burner manual. Beckett NX burners for use with direct vent systems are shipped with the controls, which provide pre and post purge. Pre purge is provided to ensure clean starts under all conditions. Post purge is provided to ensure that the boiler fires at maximum efficiency and dependability throughout the heating season. Post purge of the oil burner is controlled through the electronic circuitry supplied on the oil burner primary control. The factory set post purge timing is set at approximately one minute. Burner Installation The burner is mounted to the door with (4) 8mm studs, nuts and washers (located in the burner trim bag). Thread the (4) studs in to the (4) M8 holes threaded to permit connection to the burner. Thread the shorter length of stud into cast door. Check that the correct nozzle is pr...
